Introduction 



Important service information 



Important 



BIOS and device driver fixes are 
customer-installable. The BIOS and device drivers 
are posted on the IBM support site 

http: //www. i bm. com/pc/ support 

Advise customers to contact the PC Company 
HelpCenter at 800-772-2227 if they need assistance 
in obtaining or installing any diskette fixes. 

Customers in Canada should call IBM HelpPC at 
800-565-3344 for assistance or download 
information. 



Strategy for replacing FRUs 



Before replacing parts 



Make sure that all diskette fixes are installed before 
replacing any FRUs listed in this manual. 



Use the following strategy to prevent unnecessary expense 
for replacing and servicing FRUs: 

• If you are instructed to replace a FRU but the 
replacement does not correct the problem, reinstall 
the original FRU before you continue. 

• Some computers have both a processor board and a 
system board. If you are instructed to replace either the 
processor board or the system board, and replacing one 
of them does not correct the problem, reinstall that 
board, and then replace the other one. 

• If an adapter or device consists of more than one FRU, 
any of the FRUs may be the cause of the error. Before 
replacing the adapter or device, remove the FRUs, one 
by one, to see if the symptoms change. Replace only 
the FRU that changed the symptoms. 

Attention: The setup configuration on the computer you 
are servicing may have been customized. Running 
Automatic Configuration may alter the settings. Note the 
current configuration settings (using the View Configuration 
option); then, when service has been completed, verify that 
those settings remain in effect.

Important service information 

Strategy for replacing a hard-disk drive 

Always try to run a low-level format before replacing a 
hard-disk drive. 

Attention: The drive startup sequence in the computer 
you are servicing may have been changed. Be extremely 
careful during write operations such as copying, saving, or 
formatting. If you select an incorrect drive, data or 
programs can be overwritten. 

How to use error messages 

Use the error codes displayed on the screen to diagnose 
failures. If more than one error code is displayed, begin the 
diagnosis with the first error code. Whatever causes the 
first error code may also cause false error codes. If no 
error code is displayed, see if the error symptom is listed 
in the Symptom-to-FRU Index for the computer you are 
servicing. 

Diskette compatibility matrix

Before the computer is powered-on after FRU 
replacement, make sure all screws, springs, and other 
small parts are in place and are not left loose inside 
the computer. Verify this by shaking the computer and 
listening for rattling sounds. Metallic parts or metal 
flakes can cause electrical shorts. 

Avant de remettre I'ordinateur sous tension apres 
remplacement d'une unite en clientele, verifiez que 
tous les ressorts, vis et autres pieces sont bien en 
place et bien fixees. Pour ce faire, secouez I'unite et 
assurez-vous qu'aucun bruit suspect ne se produit. Des 
pieces metalliques ou des copeaux de metal pourraient 
causer un court-circuit. 

Bevor nach einem FRU-Austausch der Computer 
wieder angeschlossen wird, muG sichergestellt werden, 
daf3 keine Schrauben, Federn oder andere Kleinteile 
fehlen oder im Gehause vergessen wurden. Der 
Computer mu3 geschuttelt und auf Klappergerausche 
gepruft werden. Metallteile oder-splitter konnen 
Kurzschliisse erzeugen.

Prima di accendere I'elaboratore dopo che e stata 
effettuata la sostituzione di una FRU, accertarsi che 
tutte le viti, le molle e tutte le altri parti di piccole 
dimensioni siano nella corretta posizione e non siano 
sparse aH'interno deH'elaboratore. Verificare cio 
scuotendo I'elaboratore e prestando attenzione ad 
eventuali rumori; eventuali parti pezzetti metallici 
possono provocare cortocircuiti pericolosi. 

Antes de encender el sistema despues de sustituir una 
FRU, compruebe que todos los tornillos, muelles y 
demas piezas pequehas se encuentran en su sitio y no 
se encuentran sueltas dentro del sistema. 
Compruebelo agitando el sistema y escuchando los 
posibles ruidos que provocarian. Las piezas metalicas 
pueden causar cortocircuitos electricos.

A DANGER 



Though the main batteries have low voltage, a 
shorted or grounded battery can produce enough 
current to burn personnel or combustible materials. 

Bien que le voltage des batteries principales soit 
peu eleve, le court-circuit ou la mise a la masse 
d'une batterie peut produire suffisamment de 
courant pour bruler des materiaux combustibles ou 
causer des brulures corporelles graves. 

Obwohl Hauptbatterien eine niedrige Spannung 
haben, konnen sie doch bei KurzschluR Oder 
Erdung genug Strom abgeben, urn brennbare

Sebbene le batterie di alimentazione siano a basso 
voltaggio, una batteria in corto circuito o a massa 
pud fornire corrente sufficiente da bruciare 
materiali combustibili o provocare ustioni ai tecnici

Aunque las baterias principales tienen un voltaje 
bajo, una batcria cortocircuitada o con contacto a 
tierra puede producir la corriente suficiente como 
para quemar material combustible o provocar 
quemaduras en el personal.

Safety information 



Safety information 

The following section presents the safety information that 
you need to be familiar with before servicing an IBM 
mobile computer. 

General safety 

Follow these rules to ensure general safety: 

• Observe good housekeeping in the area of the 
machines during and after maintenance. 

• When lifting any heavy object: 

1 . Ensure you can stand safely without slipping. 

2. Distribute the weight of the object equally between 
your feet. 

3. Use a slow lifting force. Never move suddenly or 
twist when you attempt to lift. 

4. Lift by standing or by pushing up with your leg 
muscles; this action removes the strain from the 
muscles in your back. Do not attempt to lift any 
object that weighs more than 16 kg (35 lb) or objects 
that you think are too heavy for you. 

• Do not perform any action that causes hazards to the 
customer, or that makes the equipment unsafe. 

• Before you start the machine, ensure that other service 
representatives and the customer's personnel are not in 
a hazardous position. 

• Place removed covers and other parts in a safe place, 
away from all personnel, while you are servicing the 
machine. 

• Keep your toolcase away from walk areas so that other 
people will not trip over it. 

• Do not wear loose clothing that can be trapped in the 
moving parts of a machine. Make sure that your sleeves 
are fastened or rolled up above your elbows. If your hair 
is long, fasten it. 

• Insert the ends of your necktie or scarf inside clothing or 
fasten it with a nonconductive clip, approximately 8 
centimeters (3 inches) from the end. 

• Do not wear jewelry, chains, metal-frame eyeglasses, or 
metal fasteners for your clothing. 

Attention: Metal objects are good electrical 
conductors. 

• Wear safety glasses when you are hammering, drilling, 
soldering, cutting wire, attaching springs, using solvents, 
or working in any other conditions that might be 
hazardous to your eyes.

Safety information 

• After service, reinstall all safety shields, guards, labels, 
and ground wires. Replace any safety device that is 
worn or defective. 

• Reinstall all covers correctly before returning the 
machine to the customer. 

Electrical safety 

Observe the following rules when working on electrical 
equipment. 



~ Important 

Use only approved tools and test equipment. Some 
hand tools have handles covered with a soft 
material that does not insulate you when working 
with live electrical currents. 

Many customers have, near their equipment, rubber 
floor mats that contain small conductive fibers to 
decrease electrostatic discharges. Do not use this 
type of mat to protect yourself from electrical shock. 



Find the room emergency power-off (EPO) switch, 
disconnecting switch, or electrical outlet. If an electrical 
accident occurs, you can then operate the switch or 
unplug the power cord quickly. 

Do not work alone under hazardous conditions or near 
equipment that has hazardous voltages. 

Disconnect all power before: 

- Performing a mechanical inspection 

- Working near power supplies 

- Removing or installing main units 

Before you start to work on the machine, unplug the 
power cord. If you cannot unplug it, ask the customer to 
power-off the wall box that supplies power to the 
machine and to lock the wall box in the off position. 

If you need to work on a machine that has exposed 
electrical circuits, observe the following precautions: 

- Ensure that another person, familiar with the 
power-off controls, is near you. 

Attention: Another person must be there to switch 
off the power, if necessary. 

- Use only one hand when working with powered-on 
electrical equipment; keep the other hand in your 
pocket or behind your back. 

Attention: An electrical shock can occur only when 
there is a complete circuit. By observing the above 
rule, you may prevent a current from passing through 
your body. 



Introduction 17 



Safety information 

- When using testers, set the controls correctly and 
use the approved probe leads and accessories for 
that tester. 

- Stand on suitable rubber mats (obtained locally, if 
necessary) to insulate you from grounds such as 
metal floor strips and machine frames. 

Observe the special safety precautions when you work 
with very high voltages; these instructions are in the 
safety sections of maintenance information. Use 
extreme care when measuring high voltages. 

• Regularly inspect and maintain your electrical hand tools 
for safe operational condition. 

• Do not use worn or broken tools and testers. 

• Never assume that power has been disconnected from 
a circuit. First, check that it has been powered off. 

• Always look carefully for possible hazards in your work 
area. Examples of these hazards are moist floors, 
nongrounded power extension cables, power surges, 
and missing safety grounds. 

• Do not touch live electrical circuits with the reflective 
surface of a plastic dental mirror. The surface is 
conductive; such touching can cause personal injury and 
machine damage. 

• Do not service the following parts with the power on 
when they are removed from their normal operating 
places in a machine: 

- Power supply units 

- Pumps 

- Blowers and fans 

- Motor generators 

and similar units. (This practice ensures correct 
grounding of the units.) 

• If an electrical accident occurs: 

- Use caution; do not become a victim yourself. 

- Switch off power. 

- Send another person to get medical aid. 

Safety inspection guide 

The purpose of this inspection guide is to assist you in 
identifying potentially unsafe conditions. As each machine 
was designed and built, required safety items were 
installed to protect users and service personnel from injury. 
This guide addresses only those items. You should use 
good judgment to identify potential safety hazards due to 
attachment of non-IBM features or options not covered by 
this inspection guide. 



18 MT 2652/2653/2654 



Safety information 
If any unsafe conditions are present, you must determine 
how serious the apparent hazard could be and whether 
you can continue without first correcting the problem. 

Consider these conditions and the safety hazards they 
present: 

• Electrical hazards, especially primary power (primary 
voltage on the frame can cause serious or fatal 
electrical shock) 

• Explosive hazards, such as a damaged CRT face or a 
bulging capacitor 

• Mechanical hazards, such as loose or missing hardware 

To determine whether there are any potentially unsafe 
conditions, use the following checklist at the beginning of 
every service task. Begin the checks with the power off, 
and the power cord disconnected. 

Checklist: 

1. Check exterior covers for damage (loose, broken, or 
sharp edges). 

2. Power-off the computer. Disconnect the power cord. 

3. Check the power cord for: 

a. A third-wire ground connector in good condition. 
Use a meter to measure third-wire ground 
continuity for 0.1 ohm or less between the external 
ground pin and frame ground. 

b. The power cord should be the type specified in the 
parts list. 

c. Insulation must not be frayed or worn. 

4. Remove the cover. 

5. Check for any obvious non-IBM alterations. Use good 
judgment as to the safety of any non-IBM alterations. 

6. Check inside the unit for any obvious unsafe 
conditions, such as metal filings, contamination, water 
or other liquids, or signs of fire or smoke damage. 

7. Check for worn, frayed, or pinched cables. 

8. Check that the power-supply cover fasteners (screws 
or rivets) have not been removed or tampered with. 

Handling devices that are sensitive to 
electorostatic discharge 

Any computer part containing transistors or integrated 
circuits (ICs) should be considered sensitive to electrostatic 
discharge (ESD.) ESD damage can occur when there is a 
difference in charge between objects. Protect against ESD 



Introduction 19 



Safety information 

damage by equalizing the charge so that the machine, the 
part, the work mat, and the person handling the part are all 
at the same charge. 



Notes 




1 . Use product-specific ESD procedures 


when they 


exceed the requirements noted here. 




2. Make sure that the ESD protective devices you 


use have been certified (ISO 9000) as 


fully 


effective. 





When handling ESD-sensitive parts: 

• Keep the parts in protective packages until they are 
inserted into the product. 

• Avoid contact with other people. 

• Wear a grounded wrist strap against your skin to 
eliminate static on your body. 

• Prevent the part from touching your clothing. Most 
clothing is insulative and retains a charge even when 
you are wearing a wrist strap. 

• Use the black side of a grounded work mat to provide a 
static-free work surface. The mat is especially useful 
when handling ESD-sensitive devices. 

• Select a grounding system, such as those listed below, 
to provide protection that meets the specific service 
requirement. 



Note 



The use of a grounding system is desirable but 
not required to protect against ESD damage. 



- Attach the ESD ground clip to any frame ground, 
ground braid, or green-wire ground. 

- Use an ESD common ground or reference point 
when working on a double-insulated or 
battery-operated system. You can use coax or 
connector-outside shells on these systems. 

- Use the round ground-prong of the AC plug on 
AC-operated computers. 

Grounding requirements 

Electrical grounding of the computer is required for 
operator safety and correct system function. Proper 
grounding of the electrical outlet can be verified by a 
certified electrician.

This chapter includes descriptions for any ThinkPad model 
that has the PC-Doctor DOS diagnostics program. Some 
descriptions might not apply to your particular computer. 

Read this first 

Before you go to the checkout guide, be sure to read this 
section. 



Important notes 



Only certified trained personnel should 
service the computer. 

Read the entire FRU removal and replacement 
page before replacing any FRU. 

Use new nylon-coated screws when you 
replace FRUs. 

Be extremely careful during such write 
operations as copying, saving, or formatting. 

Drives in the computer that you are servicing 
sequence might have been altered. If you select 
an incorrect drive, data or programs might be 
overwritten. 

Replace FRUs only for the correct model. 

When you replace a FRU, make sure the model 
of the machine and the FRU part number are 
correct by referring to the FRU parts list. 

A FRU should not be replaced because of a 
single, unreproducible failure. Single failures 
can occur for a variety of reasons that have 
nothing to do with a hardware defect, such as 
cosmic radiation, electrostatic discharge, or 
software errors. Consider replacing a FRU only 
when a problem recurs. If you suspect that a 
FRU is defective, clear the error log and run the 
test again. If the error does not recur, do not 
replace the FRU. 

Be careful not to replace a nondefective FRU. 



What to do first 

When you do return a FRU, you must include the following 
information in the parts exchange form or parts return form 
that you attach to it: 

1 . Name and phone number of servicer

Service web site 

When the latest maintenance diskette and the system 
program service diskette become available, a notice will be 
posted on http://www.ibm.com/pc/partner/infotips 

Restoring the preloaded system 

If the data on a hard-disk drive is damaged or accidentally 
erased, you can restore the software that was shipped with 
the computer. This software includes the pre-installed 
operating system, applications, and device drivers. 

To restore the pre-installed software, you can use either 
the Product Recovery program or a recovery CD. 



" Ordering the recovery CD 

When the hard-disk drive is replaced because of a 
failure, no Product Recovery program is on the new 
hard disk. In this case, you must use the Product 
Recovery CD for the computer. Order the recovery 
CD and the hard-disk drive at the same time so that 
you can recover the new hard-disk drive with the 
pre-installed software when they arrive. For 
information on which CD to order, see "Recovery 
CDs" on page 171 



The Product Recovery program is in the service partition, a 
section of the hard-disk drive that is not displayed by 
Windows Explorer. 

Attention: All of the files on the primary hard-disk 
partition (usually drive C) will be lost in the recovery 
process. Be sure to back up copies of the files you have 
saved on your drive C before you begin. 

Product Recovery program 

Note: The recovery process might take up to 2 hours. 

To use the Product Recovery program to restore the 
pre-installed software, do the following: 

1. Save all files and shut down the desktop. 

2. Turn off the computer. 

General descriptions 27

Passwords 

As many as three passwords may be needed for any 
ThinkPad computer: the power-on password (POP), the 
hard-disk password (HDP), and the supervisor password 
(SVP). 

If any of these passwords has been set, a prompt for it 
appears on the screen whenever the computer is turned 
on. The computer does not start until the password is 
entered. 

Exception: If only an SVP is installed, the password 

prompt does not appear when the operating 
system is booted. 

Power-on password: 

A power-on password (POP) protects the system from 
being powered on by an unauthorized person. The 
password must be entered before an operating system can 
be booted. 

Hard-disk password: 

There are two hard-disk passwords (HDPs): 

• User HDP — for the user 

• Master HDP — for the system administrator, who can use 
it to get access to the hard disk even if the user has 
changed the user HDP 

Note: There are two modes for the HDP: User only and 
Master + User. The Master + User mode requires 
two HDPs; the system administrator enters both in 
the same operation. The system administrator then 
provides the user HDP to the system user. 



General descriptions 29 



Related service information 

Attention: If the user HDP has been forgotten, check 
whether a master HDP has been set. If it has, it can be 
used for access to the hard-disk drive. If no master HDP is 
available, IBM does not provide any services to reset 
either the user or the master HDP, or to recover data from 
the hard-disk drive. The hard-disk drive can be replaced 
for a scheduled fee. 

Supervisor password: 

A supervisor password (SVP) protects the system 
information stored in the IBM BIOS Setup Utility. The SVP 
must be entered in order to get access to the IBM BIOS 
Setup Utility and make changes to system configuration 
settings. 

Attention: If the SVP has been forgotten and cannot be 
made available to the servicer, there is no service 
procedure to reset the password. The system board must 
be replaced for a scheduled fee. 

How to remove the power-on password 

To remove a POP that you have forgotten, do the 
following: 

(A) If no SVP has been set: 

1 . Turn off the computer. 

2. Remove the battery pack. 

For how to remove the battery pack, see "1010 Battery 
pack" on page 62. 

3. Remove the backup battery. 

For how to remove the backup battery, see "1040 
Backup battery" on page 73. 

4. Turn on the computer and wait until the POST ends. 

After the POST ends, the password prompt does not 
appear. The POP has been removed. 

5. Reinstall the backup battery and the battery pack. 

(B) If an SVP has been set and is known by the servicer: 

1 . Turn on the computer; then, while the "To interrupt 
normal startup, press the blue Access IBM button" 
message is displayed at the lower-left of the screen, 
press the Access IBM button.

Power management 

To reduce power consumption, the computer has three 
power management modes: screen blank, standby, and 
hibernation. 



Notes 



• Screen blank mode is called standby mode in 
Windows NT. 

• Standby mode is called suspend mode in 
Windows NT. 



Screen blank mode 

Screen blank mode has three variants, as follows: 



General descriptions 31 



Related service information 

1 . If you press Fn+F3, or the time set on the "LCD off 
timer" in IBM BIOS Setup Utility expires, 

• The LCD backlight turns off. 

• The hard-disk drive motor stops. 

• The speaker is muted. 

2. If you are using the ACPI operating system and you 
press Fn+F3, 

• The LCD backlight turns off. 

• The hard-disk drive motor stops. 

3. If the time set on the "Turn off monitor" timer in the 
operating system expires, 

• The LCD backlight turns off. 

To end screen blank mode and resume normal operation, 
press any key. 

Standby mode 

When the computer enters standby mode, the following 
events occur in addition to what occurs in screen blank 
mode: 

• The LCD is powered off. 

• The hard-disk drive is powered off. 

• The CPU stops. 

To enter standby mode, press Fn+F4. 

Note: You can change the action of Fn+F4, if you are 
using the ACPI operating system. 

In certain circumstances, the computer goes into standby 
mode automatically: 

• If a "suspend time" has been set on the timer, and the 
user does not do any operation with the keyboard, the 
TrackPoint, the hard disk, the parallel connector, or the 
diskette drive within that time. 

• If the battery indicator blinks orange, indicating that the 
battery power is low. (Alternatively, if Hibernate when 
battery becomes low has been selected in the "Power 
Management Properties" window, the computer goes 
into hibernation mode.) 

Note for the APM operating system: 

Even if you do not set the low-battery alarm, the charge 
indicator notifies you when the battery is low, and then the 
computer enters the power-saving mode automatically. 
This default low-battery behavior is independent of the 
operating system; so if you have set the low-battery alarm, 
the computer may not do what you specified. It chooses 
either your setting or the default setting, whichever is 
appropriate. 



32 MT 2652/2653/2654 



Related service information 
If you are using the ACPI operating system, only the 
low-battery alarm is available. 

To cause the computer to return from standby mode and 
resume operation, do one of the following: 

• Press the Fn key. 

• Open the LCD cover. 

• Turn on the power switch. 

Also, the computer automatically returns from standby 
mode and resumes operation in either of the following 
events: 

• The ring indicator (Rl) is signaled by a serial device or a 
PC Card device (Windows 2000 does not support the 
ring indicator (Rl) resume by PC Card device.) 

• The time set on the resume timer elapses. In Windows 
98, the Scheduled Tasks setting takes priority over the 
Resume on timer selection in the "Power Management 
Properties" window. 

Note: The computer does not accept any input 

immediately after it enters standby mode. Wait a 
few seconds before taking any action to reenter 
operation mode. 

Hibernation mode 



" Note for Windows NT 

If you are using Windows NT in NTFS format, you 
cannot create a hibernation file. If you want to use 
hibernation mode, you will need to reinstall Windows 
NT with FAT format. 



In hibernation mode, the following occurs: 

• The system status, RAM, VRAM, and setup data are 
stored on the hard disk. 

• The system is powered off. 

Note: If the computer enters the hibernation mode while it 
is docked to the docking station, do not undock it 
from the docking station before resuming normal 
operation. If you do undock it and then try to 
resume normal operation, you will get an error 
message, and you will have to restart the system. 

To cause the computer to enter hibernation mode, do any 
of the following:

Use the following procedures as a guide in identifying and 
correcting problems with the ThinkPad computer. 

Note: The diagnostic tests are intended to test only IBM 
products. The use of non-IBM products, prototype 
cards, or modified options can lead to false 
indications of errors and invalid system responses. 

1. Identify the failing symptoms in as much detail as 
possible. 

2. Verify the symptoms. Try to re-create the failure by 
running the diagnostic test or by repeating the 
operation. 

Testing the computer 

The ThinkPad computer has a test program called 
PC-Doctor® DOS (hereafter called PC-Doctor). You can 
detect errors by running the diagnostics test included in 
PC-Doctor. This section is an overview of the procedure. 
For details that depend on model-unique functions, refer to 
"Product overview" on page 43. 

For some possible configurations of the computer, 
PC-Doctor might not run correctly. To avoid this problem, 
you need to initialize the computer setup by use of the IBM 
BIOS Setup Utility before you run PC-Doctor. On the IBM 
BIOS Setup Utility screen, press F9, Enter, F10, and then 
Enter. 

Note: When you initialize the computer configuration, 

some devices are disabled, such as the serial port. 
If you test one of these devices, you will need to 
enable it by using PS2.EXE. 

PC-Doctor cannot be used to test a device that is in the 
docking station, even if the computer supports the docking 
station. To test a USB device, connect it to the USB 
connector of the computer. To test the Ultrabay device, 
install it in the Ultrabay slot of the computer. 

To run the test, do as follows: 

Note: In the following procedure, you can select an item 
not only with the arrow keys, but also with the 
TrackPoint. Instead of pressing Enter, click the left 
button. 

1. Insert the PC-Doctor disk into the diskette drive; then 
power on the computer. 

If the computer cannot be powered on, go to "Power 
system checkout" on page 38, and check the power 
sources. 

General descriptions 35 



Checkout guide 

If an error code appears, go to "Symptom-to-FRU 
index" on page 51 . 

On the first screen, select the model and press Enter. 
Follow the instructions on the screen. 

2. The main panel of PC-Doctor appears. 

3. Select Diagnostics with the arrow keys, and press 
Enter.

• Video Adapter test supports only the LCD display on 
the ThinkPad computer. Before running PC-Doctor 
DOS, detach the external Monitor. 

• To test ZIP Drive or LS-1 20/240 Drive, each media is 
needed to be inserted before start testing. 

• To test Digital Signature Chip, the chip must be 
enabled and initialized. 

• When Legacy Floppy Drives is enabled in the IBM 
BIOS Setup Utility, Diskette Drives test is activated 
even if no legacy diskette drive is attached to the 
ThinkPad computer.

Power system checkout 

To verify a symptom, do the following: 

1 . Power off the computer. 

2. Remove the battery pack. 

3. Connect the ac adapter. 

4. Check that power is supplied when you power on the 
computer. 

5. Power off the computer. 

6. Disconnect the ac adapter and install the charged 
battery pack. 

7. Check that the battery pack supplies power when you 
power on the computer. 

If you suspect a power problem, see the appropriate one 
of the following power supply checkouts: 

• "Checking the ac adapter" 

• "Checking operational charging" on page 39 

• "Checking the battery pack" on page 39 

• "Checking the backup battery" on page 40 

Checking the ac adapter 

You are here because the computer fails only when the ac 
adapter is used: 

• If the power problem occurs only when the port 
replicator is used, replace the port replicator. 

• If the power-on indicator does not turn on, check the 
power cord of the ac adapter for correct continuity and 
installation. 

• If the computer does not charge during operation, go to 
"Checking operational charging". 

To check the ac adapter, do the following: 

1 . Unplug the ac adapter cable from the computer. 

2. Measure the output voltage at the plug of the ac 
adapter cable. See the following figure: 




Pin 


Voltage (V dc) 


1 


+15.5 to +17.0 


2 


Ground 



(16-10 V) 

3. If the voltage is not correct, replace the ac adapter. 

4. If the voltage is acceptable, do the following: 

• Replace the system board. 

• If the problem persists, go to "Product overview" on 
page 43. 

Note: Noise from the ac adapter does not always indicate 
a defect.

Checkout guide 

Checking operational charging 

To check whether the battery charges properly during 
operation, use a discharged battery pack or a battery pack 
that has less than 50 % of the total power remaining when 
installed in the computer. 

Perform operational charging. If the battery status indicator 
or icon does not turn on, remove the battery pack and let it 
return to room temperature. Reinstall the battery pack. If 
the charge indicator or icon still does not turn on, replace 
the battery pack. 

If the charge indicator still does not turn on, replace the 
system board. Then reinstall the battery pack. If it is still 
not charged, go to the next section. 

Checking the battery pack 

Battery charging does not start until the Power Meter 
shows that less than 95 % of the total power remains; 
under this condition the battery pack can charge to 100 % 
of its capacity. This protects the battery pack from being 
overcharged or from having a shortened life. 

To check the status of your battery, move your cursor to 
the Power Meter icon in the icon tray of the Windows 
taskbar and wait for a moment (but do not click), and the 
percentage of battery power remaining is displayed. To get 
detailed information about the battery, double-click the 
Power Meter icon. 

Note: If the battery pack becomes hot, it may not be able 
to charge. Remove it from the computer and leave it 
at room temperature for a while. After it cools down, 
reinstall and recharge it. 

To check the battery pack, do the following: 

1 . Power off the computer. 

2. Remove the battery pack and measure the voltage 
between battery terminals 1 (+) and 5 (-). See the 
following figure: 




Terminal 


Voltage (V dc) 


1 


+0 to +12.6 


5 


Ground (-) 



If the voltage is less than +11 .0 V dc, the battery pack 
has been discharged. 



General descriptions 39 



Checkout guide 

Note: Recharging will take at least 3 hours, even if the 
indicator does not turn on. 

If the voltage is still less than +11.0 V dc after 
recharging, replace the battery. 
4. If the voltage is more than +11.0 V dc, measure the 
resistance between battery terminals 4 and 5. The 
resistance must be 4 to 30 K 0.. 

If the resistance is not correct, replace the battery 
pack. If the resistance is correct, replace the system 
board. 

Checking the backup battery 

Do the following: 

1 . Power off the computer, and unplug the ac adapter 
from it. 

2. Turn the computer upside down. 

3. Remove the battery pack (see "1 01 Battery pack" on 
page 62). 

4. Remove the backup battery (see "Checking the battery 
pack" on page 39). 

5. Measure the voltage of the backup battery. See the 
following figure.

Symptom-to-FRU index 



Symptom-to-FRU index 

The symptom-to-FRU index in this section lists symptoms 
and errors and their possible causes. The most likely 
cause is listed first, in boldface type. 

Note: Do the FRU replacement or other actions in the 
sequence shown in the column headed "FRU or 
action, in sequence." If replacing a FRU does not 
solve the problem, put the original part back in the 
computer. Do not replace a nondefective FRU. 

This index can also help you determine, during regular 
servicing, what FRUs are likely to need to be replaced 
next. 

A numeric error is displayed for each error detected in 
POST or system operation. In the displays, n can be any 
number. 

If no numeric code is displayed, check the narrative 
descriptions of symptoms. If the symptom is not described 
there, go to "Intermittent problems" on page 57.

LCD-related symptoms 

" Important 

The TFT LCD for the notebook computer contains 
many thin-film transistors (TFTs). A small number of 
dots that are missing, discolored, or always lighted 
is characteristic of TFT LCD technology, but 
excessive pixel problems can cause viewing 
concerns. The LCD should be replaced if the 
number of missing, discolored, or lighted dots in any 
background is: 

• XGA: 8 or more bright dots, 8 or more dark dots, 
or a total of 9 or more bright and dark dots. 

• SXGA+: 11 or more bright dots, 13 or more dark 
dots, or a total of 16 or more bright and dark 
dots. 

• UXGA: 11 or more bright dots, 16 or more dark 
dots, or a total of 16 or more bright and dark 
dots. 

Note: A bright dot means a pixel is always on 

(white or color.) A dark dot means a pixel is 
always off (black color.)

Symptom-to-FRU index 

Intermittent problems 

Intermittent system hang problems can be due to a variety 
of causes that have nothing to do with a hardware defect, 
such as cosmic radiation, electrostatic discharge, or 
software errors. FRU replacement should be considered 
only when a problem recurs. 

When analyzing an intermittent problem, do the following: 

1. Run the diagnostic test for the system board in loop 
mode at least 10 times. 

2. If no error is detected, do not replace any FRUs. 

3. If any error is detected, replace the FRU shown by the 
FRU code. Rerun the test to verify that no more errors 
exist. 

Undetermined problems 

You are here because the diagnostic tests did not identify 
which adapter or device failed, wrong devices are installed, 
a short circuit is suspected, or the system is inoperative. 
Follow these procedures to isolate the failing FRU (do not 
isolate FRUs that have no defects). 

Verify that all attached devices are supported by the 
computer. 

Verify that the power supply being used at the time of the 
failure is operating correctly. (See "Power system 
checkout" on page 38.) 

1 . Power off the computer. 

2. Visually check each FRU for damage. Replace any 
damaged FRU. 

3. Remove or disconnect all of the following devices: 

a. Non-IBM devices 

b. Devices attached to the port replicator 

c. Printer, mouse, and other external devices 

d. Battery pack 

e. Hard-disk drive 

f. External diskette drive 

g. DIMM 

h. CD-ROM and diskette drive in the Ultrabay 
i. PC Cards 

4. Power on the computer. 

5. Determine whether the problem has changed. 

6. If the problem does not recur, reconnect the removed 
devices one at a time until you find the failing FRU. 

7. If the problem remains, replace the following FRUs one 
at a time (do not replace a nondefective FRU): 

a. System board 

b. LCD assembly

FRU replacement notices 



FRU replacement notices 

This section contains notices related to removing and 
replacing parts. Read this section carefully before replacing 
any FRU. 

Screw notices 

Loose screws can cause a reliability problem. In IBM 
ThinkPad computer, this problem is addressed with special 
nylon-coated screws that have the following characteristics: 

• They maintain tight connections. 

• They do not easily come loose, even with shock or 
vibration. 

• They are harder to tighten. 

• They should be used only once. 

Do the following when you service this machine: 

• Keep the screw kit (for the P/N, see "Miscellaneous 
parts" on page 178) in your tool bag. 

• Always use new screws. 

• Use a torque screwdriver if you have one. 

Tighten screws as follows: 

• Plastic to plastic 

Turn an additional 90 degrees after the screw head 
touches the surface of the plastic part: 

90 degrees more

58 MT 2652/2653/2654 



FRU replacement notices 

• Make sure you use the correct screw. If you have a 
torque screwdriver, tighten all screws firmly to the torque 
shown in the table. Never use a screw that you 
removed. Use a new one. Make sure the screws are 
tightened firmly. 

Retaining serial numbers 

This section includes the following descriptions: 

• "Restoring the serial number of the system unit" 

• "Retaining the UUID" 

Restoring the serial number of the system 
unit 

When the computer was manufactured, the EEPROM on 
the system board was loaded with the serial numbers of 
the system and all major components. These numbers 
need to remain the same throughout the life of the 
computer. 

If you replace the system board, you must restore the 
serial number of the system unit to its original value. 

Before replacing the system board, save the original serial 
number by doing the following: 

1. Install the ThinkPad Hardware Maintenance Diskette 
Version 1 .62, and restart the computer. 

2. From the main menu, select 1. Set System 
Identification. 

3. Select 2. Read S/N data from EEPROM. 

The serial number for each device is displayed. Write 
down the serial number of the system unit, designated as 
follows: 

20: System unit serial number 

After you have replaced the system board, restore the 
serial number by doing the following: 

1 . Install the ThinkPad Hardware Maintenance Diskette 
Version 1 .62 and restart the computer. 

2. From the main menu, select 1. Set System 
Identification. 

3. Select 1. Add S/N data from EEPROM. 

Follow the instructions on the screen. 

Note: The serial number of the system unit is written on 
the label attached on the bottom of the computer. 

Retaining the UUID 

The Universally Unique Identifier (UUID) is a 128-bit 
number uniquely assigned to your computer at production 



ThinkPad A30, A30p, A31 , A31 p 59 



FRU replacement notices 

and stored in the EEPROM of your system board. The 
algorithm that generates the number is designed to provide 
unique IDs until the year A.D. 3400. No two computers in 
the world have the same number. 

When you replace the system board, you must set the 
UUID on the new system board as follows: 

1 . Install the ThinkPad Hardware Maintenance Diskette 
Version 1 .62, and restart the computer. 

2. From the main menu, select 4. Assign UUID. 

A new UUID is created and written. If a valid UUID 
already exists, it is not overwritten.

Removing and replacing a FRU 



Removing and replacing a FRU 

This section presents directions and drawings for use in 
removing and replacing a FRU. Be sure to observe the 
following general rules: 

1. Do not try to service any computer unless you have 
been trained and certified. An untrained person runs 
the risk of damaging parts. 

2. Before replacing any FRU, review "FRU replacement 
notices" on page 58. 

3. Begin by removing any FRUs that have to be removed 
before the failing FRU. Any such FRUs are listed at the 
top of the page. Remove them in the order in which 
they are listed. 

4. Follow the correct sequence in the steps for removing 
the FRU, as indicated in the drawings by the numbers 
in square callouts. 

5. When turning a screw to replace a FRU, turn it in the 
direction indicated by the arrow in the drawing. 

6. When removing the FRU, move it in the direction 
indicated by the arrow in the drawing. 

7. To put the new FRU in place, reverse the removal 
procedure and follow any notes that pertain to 
replacement. For information about connecting and 
arranging internal cables, see "Locations" on page 142. 

8. When replacing a FRU, use the correct screw as 
shown in the procedures. 



A DANGER 



Before removing any FRU, power off the computer, 
unplug all power cords from electrical outlets, 
remove the battery pack, and then disconnect any 
interconnecting cables. 



Attention: Before the computer is powered on after FRU 
replacement, make sure that all screws, springs, and other 
small parts are in place and are not loose inside the 
computer. Verify this by shaking the computer gently and 
listening for rattling sounds. Metallic parts or metal flakes 
can cause electrical short circuits. 

Attention: The system board is sensitive to, and can be 
damaged by, electrostatic discharge. Before touching it, 
establish personal grounding by touching a ground point 
with one hand or by using an electrostatic discharge (ESD) 
strap (P/N 6405959).
